I just purchased a 198? 16 for us to play with this summer

. I stepped the mast and the shrouds and forestay seem very loose. Without bringing the mast to far forward what would be the best way to take out the slack? How firm should I make the shroud and forestay? Also, can I get replacement bushings for some of the bolts and what should I use to close up around the shroud anchors in the hull?
tks,
